The xpack.profiling.templates.enabled setting in Elasticsearch controls whether the profiling templates are automatically created and updated. These templates are essential for the proper functioning of the profiling feature in Elasticsearch.
- Default Value:
true - Possible Values:
trueorfalse - Recommendation: It is generally recommended to keep this setting enabled unless you have specific reasons to manage profiling templates manually.
This setting determines if Elasticsearch should automatically manage the index templates required for the profiling feature. When enabled, Elasticsearch ensures that the necessary templates are created and updated as needed, which is crucial for storing and analyzing profiling data effectively.
This setting is available in Elasticsearch 7.5 and later versions.
Reason for Change: You might disable this if you want to manage profiling templates manually or if you're experiencing conflicts with custom templates.
Effects: Disabling this setting means you'll need to manage profiling templates manually, which could lead to issues if not done correctly.
Common Issues
- Profiling data not being indexed correctly when templates are disabled.
- Conflicts between custom templates and automatically managed profiling templates.
Do's and Don'ts
Do's:
- Keep this setting enabled unless you have a specific reason to manage templates manually.
- Monitor template changes if you disable this setting.
Don'ts:
- Don't disable this setting without a plan to manage profiling templates manually.
- Avoid creating custom templates that conflict with profiling templates.
Frequently Asked Questions
Q: What happens if I disable xpack.profiling.templates.enabled?
A: If disabled, Elasticsearch will not automatically create or update profiling templates. You'll need to manage these templates manually to ensure proper functioning of the profiling feature.
Q: Can I modify the profiling templates if this setting is enabled?
A: While it's possible, it's not recommended. Any modifications may be overwritten when Elasticsearch updates the templates automatically.
Q: How often are profiling templates updated?
A: Profiling templates are typically updated during Elasticsearch version upgrades or when significant changes to the profiling feature are introduced.
Q: Will disabling this setting affect existing profiling data?
A: Existing data won't be affected, but new profiling data may not be indexed correctly if the templates are not properly maintained.
Q: Is it safe to enable this setting after it has been disabled for some time?
A: Yes, it's safe. Elasticsearch will check and update the templates as needed when the setting is re-enabled.
